One of the disadvantages of the large-scale glass façades used in modern architecture is that they cause indoor temperatures to rise sharply in the summer. Air-conditioning already devours 15 percent of the total energy consumed in Europe, and more in the US. Researchers from the Fraunhofer Institute for Solar Energy Systems ISE teamed up with BASF to develop an environmentally-friendly alternative to air-conditioning systems. The team of researchers was nominated for the German Future Prize for their innovation comprising a microencapsulated latent heat storage material for construction materials.
